' CHAIR.

Specification of Letters Patent.

Patented Sept. .28, 1920.

Application filed September 1, 1917. Serial No. 189,397.

To aZZ wwm 2'23 may concern:

Be it known that I, HAROLD ROVNIREE, a citizen of the United States, residing at Kenilworth, county of (look, State of lllinois, have made a certain new and useful Invention in Chairs, of which the following is a specification.

This invention relates to chairs, settees, and the like.

The object of the invention is to provide a chair which is simple in structure, durable, and economical of manufacture.

A further object of the invention is to provide a chair, settee, or the like, which may be tilted backwardly to any desired degree for convenience or comfort.

A further object of the invention is to provide means for preventing a chair, settee, or the like, from ovei*turning due to the backwardly tilting position thereof.

A further object of the invention is to provide a chair which may be readily tilted from one position to another by means of the foot without necessitating excessive manual labor or inconvenience of being compelled to stoop over to manipulate the tilt-- ing mechanism.

Further objects of the invention Will appear more fully hereinafter.

The invention consists substantially in the construction, combination, location and relative arrangement of parts, all as Will be more fully hereinafter set forth, as shown by the accompanying drawing, and finally pointed out in the appended claims.

Referring to the drawingr Figure 1 is a bottom view of a chair embodying my invention.

Fig. 2 is a view in section taken on the line 2, 2, Fig. 1, looking in the direction of the arrows.

Fig. 3 is a sectional view taken on the line 3, 3, Fig. 2, looking in the direction of the arrows.

Fi 4 is a sectional view taken on the line 4, 4, Fig. 1, and looking in the direction of the arrows.

Fig. 5 is an enlarged detailed view inverted of the latch mechanism employed in ac-v cordance With my invention.

The same part is designated by the same reference numeral wherever it occurs throughout the several views.

It is among the special purposes of my present invention to provide a chair which passes through the bracket 8.

may be tilted backwardly to any desired degree for the purpose of reclining therein, and in connection therewith to afEord a simple and durable and efficient means for the rear legs or supports of the chair to be shifted or inclined rearwardly in accordance with the degree of tilting of the chair body. It Will be understood however that while I have mentioned my invention as applied to chairs and Will hereafter describe a chair constructed in accordance therewith, the invention is equally well adapted to be applied to settees, couches, or similar articles of furniture used for similar purposes.

Referring to the drawing I show a chair structure of the usual type comprising a back portion 1, arm rests 2, and a scat structure 3, all rigidly secured to each other, and the front legs 4 being likewise rigidly secured to the seat 3. The rear legs 5 are secured to a strip 6, which strip is pivotally secured to the scat 3, for example, by means of the hinge 7 to allow the legs 5 to move rearwardly when the chair is tilted and thereby prevent the chair from turning over from its tilted position. Secured to the under surface of the scat 3 is a bracket 8 provided With an inclined groove 9, which groove is provided with a plurality of indentations 10. T0 brace the respective front legs 4 relative to each other and to the scat I provide a rod 11 secured to the legs 4 at its ends and passing through the bracket 8 at the portion 12 thereof. It Will be seen that this rod is of a substantial V-shape with the apex of the V at that portion which A similar substantially V-shaped rod 13 vvith its apex opposed to that of the rod 11 is pivotally secured at its ends to the respective rear legs 5 and passes through the bracket 8 at the apex of its V through the slot 9. It will be seen. that inasmuch as the legs 5 are pivot ed and as the rod 13 passes through the slot 9 of the bracket 8. the legs 5 can be moved backwardlv a distance equivalent to the length of the slot 9 of the bracket 8. The depressions from the slot 9 as is shown best in Fig. 2 extend dovvnwardly and rearwardly, or are inclined downwardly in a rearward direction, so that if the rear legs 5 are in their farthest backward position, as indicated bv dotted limes, Fig. 2, pressure on the legs in a forward direction Will move the legs to assume their upright position thereby facilitating the quick ohanging of the chairs position from an inclined one to an uprightone. VVhen the legs are tilted backWard it is obvious that the re ar end of the seat 3 drops in proportion to the distance the rear legs have moved, thereby regulating the degree of tilting of the chair. When the chair is in its upright position as shown in Fig. 2, to drop it to any one of its tilted positions upward pressure, say, by the foot, on the rod 13 disengages the rod from the depression 10 of the slot 9 and causes the rod to raise to the slot 9 and thus it can be dropped to any desired notch o depression 10 aceoiding tothe desire.

While I have shown in the illustration of one embodiment of my invention a chair of wood I wish 'it to be underst0od that the chair, or settee, or the like, may be made of any desirable material, for example, it is an exceedingly compact and efficient structure for a steel or other metal chair; 'likewise, while I have shown the braoket 8 as being provided with three positions of tilting, it is to be understood that any desired number of tilted positions may be supplied, and also that any desired degree of tilting may be secured by ordinary changes in detail of the bracket, such asthe degree of slant of the slot 9, the number of depressions 10, which changes of detail will readily ocour. to those skilled in the art without departing from the spirit or scope of my invention as defined.

in the olaims; I also wish it to be understood that many other lchanges {in detail will readily occur to those skilled in the art withont departing from my invention; therefore, what I claim as new and useful, and of my own invention, and desire to secure by Letters Patent, is,

1. The combination with a seat, a back, and front support rigidly secured together, a rear support pivotally connected to said seat, and a single braoket carried beneath said seat at the approximate conter thereof and adjustably connected to said rear support for oontrolling the degree of pivotal rnovement threof relative tosaid scat,-

2. The combination With a seat, a back and front legs rigidly secured together, rear legs pivotally oarried by said seat, a braket carried beneath said seat, and an adjustable connection between said bracket and said rear legs, and a rigid connection between said bracket and said front legs.

3. The combination with a seat, a back and front legs rigidly secured together, rear legs pivotally carried by said seat, a bracket oarried beneath said seat, said bracket provided with an upwardly inclined slot, and a brade connecting said rear legs and passing through said slot.

4. The combination with a seat, a back and front legs rigidly secured together, rear legs pivotally carried by said seat, a bracket carried beneath said seat, said braoket provided 'with a longitudinally extending slot, and a conneotion between said rear legs and said bracket slidably located in said slot.

5. The combination with a seat, a back and front legs rigidly secured together, rear legs pivotally carried by said seat, a bracket Carried beneath said seat, said bracket provided with an upwardly extending slot having a plurality of rearwardly extending depressions therein, and a brace conneoting said rear legs and passing through said slot.

6. The combination with a seat, a back and front legs rigidly secured together, rear legs pivotally carried by said seat, a braoket carried beneath said seat, said bracket provided with a longitudinall'y extending slot having a plurality of rearwardly entending depressions therein, and a connection between said rear legsand said bracket slidably located in said slot.

7. The combination with a seat, a baok and front legs rigidly secured together, rear legs pivotally carried by said seat, a bracket carried beneath said seat, said bracket provided with an upwardly extending slot hav vided with a longitudinally extending slot having a plurality of rearwardly eXtending depressions therein extending clownwardly and rearwardly, and a connection'between said rear legs and said bracket slidably lo= catod in said slot.

In testimony whereof I have hereunto set my hand on this 14th day of August, A. D.

HAROLD RO'WNTREE.
